Definitions
- the present invention concerns a machine for processing polymer materials.
- the present invention concerns a machine comprising a stator and rotor rotatable around an axis of rotation and coupled with the rotor, and a processing channel between the stator and the rotor for processing the polymer materials.
- the invention refers in general to machines of the type identified above and configured to process polymer materials by melting or mixing or degassing of at least two components, the first of which is a viscous liquid and the second another viscous liquid or a solid in particles or a gas or a combination of the above-mentioned elements.
- the machines for processing polymer materials of the type identified above comprise screw machines or screw extruders in which a screw is rotatable inside a cylinder so as to define a helical processing channel.
- the screw machines have some drawbacks .
- the flow rate of polymer material is limited by the fact that the width of the flow channel is a function of the screw pitch which, in turn, is a function of the angle of the screw and the thickness of the screw thread, and by the fact that there are two speed components of the flow of polymer material, only one of which contributes to the flow of the material towards the outlet, determining the ejection flow rate.
- the flow of polymer material has a speed component parallel to the threads, a function of the cosine of the screw angle, and a speed component perpendicular to the threads, a function of the sine of the screw angle, which does not contribute to the flow of the material inside the channel, towards the outlet.
- the screw machines also have further problems such as insufficient and inefficient elongational dispersion of the liquid, insufficient and inefficient degassing of the liquid- gas binary mixtures, and insufficient and inefficient melting of the solid thermoplastic substances.
- the process problems are connected with the passage of the liquid particles through the gap between the thread and the cylinder.
- a considerable number of liquid particles are arranged along the trajectory parallel to the threads, instead of along the circumferential trajectory perpendicular to the threads, escaping from the desired process.
- a known solution is to increase the local circumferential flow rate of the extruder by elongation of the sections concerned. This increases the probability of all the particles being "deformed" in the desired way.
- the required flow rate increase is normally very significant and ranges from a theoretical minimum of 4,6 times to over 20 times the ejection flow rate.
- the design of mixing or degassing areas much longer than necessary results in considerable drawbacks including higher investment, greater space occupied, lower energy efficiency and the risk of degradation of the polymer materials.
- screw machines are subject to fouling in the area of the degassing flue.
- the degassing takes place through the thin film of liquid that forms above the surface of the cylinder, at the liquid/gas interface. Since at least one fraction, however small, of polymer material must necessarily come into contact with both the cylinder and the screw to permit the feed thereof, this fraction of material that comes into contact with both the cylinder and the screw is obliged to pass in front of the degassing flue, once every turn, and therefore "dirties" the flue area.
- a machine for processing polymer materials, the machine comprising a rotor rotatable around an axis of rotation; a stator sealingly coupled with the rotor; at least one circumferential recess which extends along an angle of less than 360° in the stator and forms with the rotor a processing channel for the polymer material; at least one inlet channel for feeding the polymer material to the processing channel; and one outlet channel for evacuating the polymer material from the processing channel.
- the recess extends in an annular direction orthogonal to the axis of rotation.
- the speed of the polymer material has one single component and, in the vicinity of the rotor wall, corresponds substantially to the speed of the rotor, when the material is liquid.
- the recess has a constant width measured parallel to the axis of rotation. The constant width allows a regular flow rate of polymer material.
- non-constant widths, around the circumference of rotation can be provided without any problem, for example to promote two-dimensional elongation of the liquid.
- the bottom face of the recess is arranged at a distance from the rotor so as to determine a variable height of the processing channel.
- variable height of the processing channel allows the design of processing channels having different purposes such as the melting or degassing of the polymer material or the infiltration or dispersion of agglomerates of elementary solid particles in the polymer matrix or, lastly, the dispersion of one or more liquids in one or more further liquids.
- the processing channel comprises a first portion arranged at the inlet channel having a constant height; a second portion arranged at the outlet channel having a constant height lower than the height of the first section, with pumping effects, and a third portion included between the first and the second portion, having gradually decreasing height with an initial height equal to that of the first portion and a final height equal to that of the second portion.
- the configuration of the first portion serves to stabilise the material; the configuration of the third portion serves to compress the solid material on the surface of the rotor or to "lengthen” the liquid material, imparting elongational type stress, while the configuration of the second portion serves to generate positive pressure gradients to overcome the pressure losses at the outlet.
- the third portion arranged between the first and the second portion contains a series of converging areas, each followed by diverging areas. The reason for this variation is to provide a plurality of sequential converging areas, by increasing the number of "elongations" which the material is forced to undergo before coming out of the processor.
- the processing channel comprises a first portion having a constant height and a third portion having a constant height lower than the height of the first portion, with pumping effects.
- This configuration is particularly preferred for degassing liquid mixtures. In this configuration the liquid is spread like a thin film on the surface of the rotor, so that a significant constant distance forms, for example of a few millimetres, between the surface of the exposed film and the wall above the cylinder.
- the creation of a constant vacuum on the exposed face of the film is particularly easy and effective.
- the thickness of the film is determined by the density of the liquid, the width of the channel, the volumetric flow rate of the liquid and the speed of the rotor and by other material parameters such as the diffusion coefficient of the gas through the liquid.
- the rotor has a smooth cylindrical outer face.
- the processing channel is provided completely in the stator.
- the machine comprises a feed channel for feeding to the processing channel agglomerates of elementary particles configured to be infiltrated and dispersed respectively in a polymer matrix.
- This configuration allows composite polymer materials to be obtained.
- the inlet channel comprises two inlet mouths arranged in sequence along the processing channel upstream and downstream respectively of the aperture for feeding the agglomerates of elementary particles so as to feed the agglomerates between two layers of liquid polymer material.
- the machine comprises a degassing channel configured to eject the gases generated during processing of the polymer material.
- the machine comprises a recirculation system for recirculating, outside the processing channel, a fraction of polymer material in the liquid/pasty state which escapes from the opposite sides of the processing channel, due to the positive pressure gradient that forms along the path in the direction of the outlet, again in the processing channel, preferably returning to the central area of the processing channel.
- This system has proved to be excellent for eliminating the liquid leaks through the lateral seals in the vicinity of the bearings, since the recirculation flow rate of the escaped liquid is much greater than the flow rate of the lateral leak.
- the stator comprises a body; and a tubular element arranged around the rotor and in sliding contact with the rotor, and sealingly coupled with the body; said at least one recess being formed along the inner face of the tubular element .
- This construction embodiment is particularly simple and advantageous .
- tubular element facilitates the provision of conduits having complex forms inside the stator.
- the tubular element has at least one further recess formed along the outer face of the tubular element and configured to define, in part, the processing chamber liquid inlet conduit .

- the machine 1 comprises a rotor 2 and a stator 3.
- the rotor 2 is supported rotatably around an axis of rotation A and is coupled to the stator 3.
- the rotor 2 comprises a smooth cylindrical (with circular base) outer face 4, i.e. substantially without grooves, notches or recesses.
- the stator 3 has a seat 5 for housing the stator 2 defined by a cylindrical inner face 6 (cylinder with circular base) .
- the outer face 4 of the rotor 2 and the inner face 6 of the seat 5 of the stator 3 are concentric and facing and have respective radiuses of curvature such that the play between the rotor 2 and the stator 3 is reduced to a minimum within the tolerances that allow easy rotation of the rotor 2 with respect to the stator 3.
- a recess 7 is formed in the seat 5.
- the recess 7 extends in a circumferential direction along the face 6 by an angle of less than 360°.
- the recess 7 extends by an angle slightly greater than 180°.
- the recess 7 faces the rotor 2 and defines with the rotor 2 a processing channel 8 of the polymer material.
- the recess 7 has a bottom face 9 and two lateral faces 10, only one of which is illustrated in figure 1.
- the height H of the processing channel 8 is defined by the distance in a radial direction between the outer face 4 of the rotor 2 and the bottom face 9 of the recess 7, while the width W of the processing channel 8 is defined by the distance in an axial direction between the lateral faces 10 of the recess 7.
- the lateral faces 10 are parallel to one another and define an annular and not helical processing channel 8.
- the height H is as a whole variable, while the width W is maintained normally constant as a consequence of the parallelism of the lateral faces 10.
- the height H has a first value constant along a first arc of approximately 10°, increases abruptly to a second value and then increases slightly along an arc of approximately 90°. The height H is then abruptly reduced and again remains constant along the remaining part .
- the machine 1 comprises an inlet channel 11 for feeding the polymer materials to the processing channel 8, and an outlet channel 12 for evacuating the polymer materials from the processing channel 8.
- the processing channel 8 extends between the outlet of the inlet channel 11 and the inlet of the outlet channel 12. It should be noted that the machine 1, when used for processing liquids, has an inlet channel 11 shaped so as to lower the height of the processing channel 8 in the vicinity of the outlet of the inlet channel 11. Said lowering, as already mentioned, extends by an arc of approximately 10°.

- Figure 3 shows the processing channel 8 arranged on rectangular coordinates, with the polymer material entering in granular solid form and being melted to become a liquid after a certain portion in the direction of the arrow.
- the reduction in the height H of the processing channel 8 when used to melt thermoplastic solids, has the purpose of both compensating the space which is reduced due to the apparent density of the solids which is lower than the density of the melted mass and of facilitating infiltration of the newly formed melted material into the interstices between the solid particles so as to increase the interface between the solid material and the material in the liquid/pasty state and, thus, the efficiency of the melting process.
